rREssURE RoLL RELEASE FOR CLOTHES-WRINGERS.

Specifidation of Letters Patent. 7 Patented Mar. 20, 1917- Application filed September 9,1916: Serial No. 119,176.

To all whom it may concern: Be it known that I, JOHN F. HEMENWAY,

I a citizen of the United States, residing at simple and cheap in construction, and onewhich can be readily applied to the ordinary construction of clothes wringer now in use.

Another object of my inventionv is to provide a. pressure release which is operated by a centrally disposed member carried by the top bar so that when the same is depressed, the retaining members will be released in order to release the pressure on the pressure rolls so that in case of an accident or foreign object becoming caught between the rolls the pressure can be instantaneously released.

Another and further object of the inven tion is to provide a pressure release which is so constructed that the same can bequickly attached to a clothes wringer and detached therefrom so as to convert an or-,

dinary clothes wringer into a safety wringer with pressure releasing means for the pressure rolls.

' Other and further objects and advantages of the invention will be hereinafter set forth tion of a clothes wringer showing the application of my improved construction of pressure release thereto; and v Fig. 2 is a top plan view of the same. Like numerals of reference refer to like parts in the several figures of the drawing.

In the drawing I have shown the application of my invention to a clothes wringerof the ordinary construction comprising a frame 1 having slotted side barsin which are mounted bearings for the shafts 2 and 3 of the pressure rolls 4 and 5 which are provlded with the usual meshing gears inclosed by a casing,the upper bearings 3 car rying spring-supports 6 on which are arranged pressure springs 7 engaged by bearing plates 8 carried by a pressure bar 9.

Slidably mounted within the slotted upper end portions of the slotted side bars of the wringer frame, is a top bar 10 which is provided with threaded boxes 11 in Which are mounted pressure screws 12 which engage the plates ,8 of the pressure bar 9 in order to exert the pressure in the pressure spring so that the rolls will be held under tenslon. I

Secured to each of the side bars of the wringer frame is a keeper 13 which is in the form of a block of metal secured to the inner face of the side bar to one side of the slot, and it will be noticed that in placing these keepers in position, one is arranged on one side of the top bar 10 and the other is arranged upon the opposite side. secured to the top bar 10 adjacent each end is a depending bracket 14 on each of which is mounted a pivoted latch 15*co6peratingwith the keeper 13 as clearly shown in Fig. 1 in order to hold the top bar 10 in predetermined position so that the pressure screws can exert the pressure on the pressure rolls through the medium of the pressure bar and pressure springs. Each of the pivoted latches 15 is provided with a tail portion 16 which is 'pivotally mounted on a transversely arranged, pin 17 carried by the lower end of. the shank 18 of a push button 19 which is slidably mounted in a bore 20 formed in the top bar 10 and surrounded by a coil 'spring'21 as shown in Fig. 1 so that the push button 19 is normally held in the position shown in Fig. 1 in order to hold the pivoted latches 15 under the keepers 13 so that the top bar will be held in its proper position within the wringer frame.

- When itis desired to instantaneousl re. lease the pressure on the pressure rol s by striking the push button 19 the ivoted latches 15.will' be .thrownput of contact with the keepers 13 so as to allow the top frame which will instantaneously release the pressure means so as to allow the upper pressure roll to move vertically.

From the foregoing description it will be seen that in order to apply my improved construction of pressure release to a clothes wringer of the ordinary construction,.'it is only necessary to bore a hole to form a bearing for the shank of the push button and to secure the keepers and brackets respectively to the top bar and side bars of the .wringer frame.

I claim: I

1. A clothes wringer comprising a frame having pressure rolls and pressure means for said rolls, a top bar movably mounted within said frame having pressure screws for adjusting said pressure means, keepers secured to the inner faces of the side bars having pressure rolls and pressure means for said rolls, a top bar movably mounted within said frame having pressure screws for adjusting said pressure means, keepers carried by the side bars of said frame, pivoted latches carried by said top bar engaging said keepers, and a push button slidably mounted within the top bar having a connection with said latches for moving said latches out of contact with said keepers to release said top bar.

3. A clothes wringer, comprising a frame having pressure rolls and pressure means for said rolls mounted therein, a movably mounted top bar carrying means for adjusting said pressure means, keepers carried by the sidebars of said frame, brackets carried by the top bar of said frame, pivoted latches mounted on said brackets en aging said keepers, and a spring actuate push button mounted in said top bar having a connection with said latches.
